Days after the alleged crime, ASU Police Chief Jim Graboys said campus police were "aggressively investigating" the incident, but due to federal and state laws little information can be released.

Graboys issued the following statement on the investigation today:

"The ASU Police Department is thoroughly and methodically looking into each and every lead developed in this ongoing investigation. The investigative and judicial processes require that certain levels of evidence must be developed prior to the naming or charging of any suspect in an offense. At the present time, all leads are being followed and considered, including any submitted to us from any source. When we have gathered viable, accurate and pertinent evidence to allow us to arrest, name and charge a specific suspect that information will be made available to the public."

The assailant is described as a short and stocky black man, who was possibly armed when he left campus.

An alert was issued to ASU students, and the residence hall staff was notified in person, after the incident was reported.
